We apply a monthly water-balance model (MWBM) to simulate components of the water balance for the period 1950-2099 under RCP4.5 and RCP8.5 for the Contiguous United States. We use the statistically downscaled MACAv2-METDATA temperature and precipitation data from 20 General Circulation Models (GCMs) from the Climate Model Intercomparison Program Phase 5 (CMIP5) as input to the water balance model. This dataset supports the USGS National Climate Change Viewer. The statistically downscaled dataset is: MACAv2-METDATA: Multivariate Adaptive Constructed Analogs (Abatzoglou & Brown, 2012, bias corrected by METDATA, Abatzoglou, 2013) Users interested in the downscaled temperature and precipitation files are referred to...
We collected diets on Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and brown trout (Salmo trutta) above (Yellowstone cutthroat trout allopatry) and below (Yellowstone cutthroat trout sympatry with brown trout) a natural barrier in Duck Creek, Montana. We used gastric lavage methods to collect diets, and samples were placed in storage containers and taken back to our lab and frozen until sorting. All samples were sorted by Rhithron, Inc. (Missoula, MT) with individuals identified down to the order.
Aeroecology focuses "on the planetary boundary layer, or aerosphere, and the myriad of organisms that, in large part, depend upon this environment for their existence" (Kunz et al. 2008). The primary mission of the Aeroecology Community is to act as a clearing house for remotely sensed data related to biological use of the aerosphere. This community aims to provide biological data collected from weather radar, portable radar, thermal imaging, and other applicable and emerging technologies.
With increasing concerns about the impact of warming temperatures on water resources, more attention is being paid the relationship between runoff and precipitation, or runoff efficiency. Temperature is a key influence on Colorado River runoff efficiency, and warming temperatures are projected to reduce runoff efficiency. Here, we investigate the nature of runoff efficiency in the upper Colorado River (UCRB) basin over the past 400 years, with a specific focus on major droughts and pluvials, and to contextualize the instrumental period. We first verify the feasibility of reconstructing runoff efficiency from tree-ring data. The reconstruction is then used to evaluate variability in runoff efficiency over periods...

An area encompassing all the National Forest System lands within the Greater Yellowstone Ecosystem (GYE) administered by an administrative unit. The area encompasses private lands, other governmental agency lands, and may contain National Forest System lands within the proclaimed boundaries of another administrative unit. All National Forest System lands fall within one and only one Administrative Forest Area.
We investigated the dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem (GYE) using serological data collected from 1984 to 2014. 565 sera samples were obtained from 425 unique grizzly bears (134 females and 291 males) from 1984 to 2014 and 319 sera samples were obtained from 285 unique wolves (130 females and 155 males) from 1996 to 2014. Here we provide the unique identifier for each individual, the species and sex, the date the individual was captured, the estimated birth year and age, and the CDV antibody titer results based upon serum neutralization assays.

The focus of this dataset is soil temperature collected on four mountain summits in Glacier National Park, Montana, USA from 2003 through 2018. Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt. Seward, also east of the continental divide. These four summit sites comprise a target region set up in accordance with the Global Observation Research Initiative in Alpine Environments (GLORIA). GLORIA was initiated by the University of Vienna in 2000 and protocols for operating target regions have been refined and revised since then. Sixty-nine GLORIA target regions now exist throughout the...
This dataset is focused on alpine plant species presence/absence, species turnover, and trends in species abundance on four mountain summits in Glacier National Park, Montana, USA from 2003 through 2014. Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt. Seward, also east of the continental divide. This multi-summit approach to monitoring alpine plant species follows the protocols of the Global Observation Research Initiative in Alpine Environments (GLORIA) that were initiated by the University of Vienna in 2000 and which have been refined and revised since then. GLORIA summit sites...

These datasets contain aquatic macroinvertebrate and water quality data collected from 159 wetlands in Montana and North Dakota within the Prairie Pothole Region of the Williston Basin.
False positive occupancy analysis predictions with model uncertainty based on summertime data provided to support the three bat species status assessment (SSA) for Myotis lucifigus (MYLU), Myotis septentrionalis (MYSE), and Perimyotis subflavus (PESU). The objectives outlined by the Fish and Wildlife Service's SSA team were to estimate summertime distributions across the entire species range. Statistical analysis included five types of response data requested from the North American Bat Monitoring Program database (NABat): automatically identified stationary acoustic calls, manually vetted stationary acoustic calls, automatically identified mobile acoustic calls, manually vetted mobile acoustic calls, and capture...
USGS scientists evaluated the utility of hidden Markov movement models to characterize seasonal movements of mule deer (Odecoileus hemionus) and pronghorn (Antilocapra americana) that were tracked with GPS collars in Wyoming, USA, during 2014-2021. Data include step lengths and turning angles for individual animals at daily time-steps throughout the tracking period. Models demonstrated distinct seasonal movements between species indicative of migratory behavior and enable analyses to identify influential factors that affect decisions to migrate by animals.

This WSR-88D weather radar dataset includes different types of scatterers hand-screened and identified based on a combination of scientific literature and media reports of biological events, knowledge of animal natural history in confirming radar sweeps characterized by a given type, and a re-evaluation and subsampling process to avoid inclusion of non-focal types. The dataset is comprised of eight scatterers, seven biological and one meteorological: trans-gulf migrants, purple martins (Progne subis), waterfowl and sandhill cranes, black-necked grebes (i.e., eared grebe, Podiceps nigricollis), Brazilian free-tailed bats (Tadarida brasiliensis), diurnal insects, mayflies and midges, and precipitation. This dataset...
